It is of Y course -essentia'l-in' a can assembly of this. kind; that the slide valve be -lockedrin'-the" tube during-shipment; so' that it-will not in 2'0 advertentlyreleasemilk from the'rcarr. The-Tam minga; patent: ref erred: to discloses a satisfactory arrangement for accomplishing: this result; In the structure there shown;- the outer end'ofwthei delivery tube is flaredi's'o as toprovide an external? flanges: The: slide valve" is fitted into the outer endlidf'the? tube" and comprises a: meta'lz clipeprovided with opposite-1w projecting bendable: tongues; When the can is. fil'led'for shipment: at: the 'creamery these: tongues: are =bent1 'oventh'e fia'nge of the delivery tube and 'serve tolock the: valve firmly in the outer end of the tube until the retailer receives the can and is ready to hook up the valve to appropriate valve operating mechanism. a

In the past the attachment of the bendable tongues of the slide valve clip to theflangeof the delivery tube has been accomplished manually, by bending'these tongues in such a wayas to engage theflange and lock the valve in position; The manual operationv however; has provedi very unsatisfactory .for many reasoned It is i a slow prdcess-fanid requiressome little skillito doitzproprerly. Moreover it is almost impossible to uniformly bend these tongues by hand and a fair degree of uniformity is required so that the tongues may be subsequently released from the flange of the tube by disengaging means forming a part of the valve operating means. The present invention provides a very satisfactory device whereby the bendable tongues of a slide valve clip, such as described, may be readily bent at the creamery or other source of bulk milk supply when reparing the can for shipment. The device is such as to I Cfa'fmi.

Figure 4 is a view, partly in elevation and partly in section, of the milk delivery tube with attached slide valve, the full line positions of the tongues produce uniform bending in a simple and expedibeing those occupied prior to bending and the 3 dotted line position showing the finally bent positions of these tongues.

Referring to the drawings, l indicates the base of the device. It is conveniently in the form of a, casting although it may be fabricated in any other manner. In any event, it is provided with a longitudinal guide channel 2 in which are positioned two slides 3 and 4 which respectively carry upstanding bending jaws 5 and 6, the opposing faces I and 8 of which are shaped to cooperate with the tongues to be bent. To insure alinement between the slides 3 and 4 at all times, the slide 3 carries a fixed centering pin 9 which slidably extends into a hole I in the slide 4, as shown best in Fig. 2. The slides are maintained in the channel 2 by means of a cover plate H resting on top of the base i and firmly fixed thereto by means of screws I2. The center of the plate is cut away, as shown at 13, so that the jaws and 6 may project upwardly therethrough and in practice the rear edge M of the opening l3 forms an attachment against which the back of the jaw 5 engages in a relatively fixed manner, only the jaw 6 being movable in the construction shown.

Between the jaws the respective slides are pro vided with raised platforms l5, substantially flush with the upper surface of the plate II and back of these platforms the plate I I has attached thereto a strip of metal, the front edge It of which forms an abutment to properly position the valve for eoaction with the jaws. An operating handle I! is pivoted to the base i by means of a screw and is connected by a link [9 to the slide 4. This handle is relatively long so as to give sufiicient leverage to permit of operation of the jaw 6 with considerable force through the application of relatively little manual energy.

In Figures 2 and 3 is shown a milk delivery tube 20, the outer end of which is provided with an external flange H. The metal clip 22 of the slide valve projects'into the outer end of the tube and has at its outer end an annual flange 23 provided with oppositely projecting bendable tongues 24.

In utilizing the present invention with a structure of this kind the slide valve is manually inserted into the outer end of the tube and the parts as thus assembled are then placed in upright position upon the platform I5 with the back edge of the flange engaging the stop [6. The handle I! is then operated in a clockwise direction to force the jaw 6 toward the jaw 5 and the shaping of the jaws is such as to cause the tongues to be bent inwardly over the flange 2| of the tube, so as to draw the flange 2| tightly down against the flange 23 and clamp these parts firmly together. When this has been accomplished the tongues will have partaken of the position shown in dotted lines of Fig. 4 where they will remain to hold the parts in proper assembled relation until subseforms, it is shown in the drawings as embodying an adjustable stop 25 adapted to be locked in adjusted position by means of screws 26 and so arranged as to be engaged by the handle I! when the tongues have been bent as much as desired and necessary.

After the bending operation has been completed, the handle is swung to the right in Fig. l, to release the delivery tube and prepare the device for operation upon the next tube. To hold the device in place while it is being operated, the base I is preferable provided with holes 21 for attaching the device to a bench or table.

Experience with the structure hereinbefore described has shown it is capable of assembling valves and outlet tubes at a greater speed and with much more uniformity than could possibly .be accomplished by hand and its use insures the proper functioning of the valve releasing devices of the dispensing means with which the tubes hereinbefore referred to are adapted to cooperate.

The foregoing detailed description sets forth the invention in its preferred practical form, but the invention is to be understood as fully commensurate with the appended claim.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent is:

A device for attaching a slide valve provided with bendable tongues to a delivery" tube having a flanged outer end comprising: a base provided with a guide channel, a cover plate positioned on the base and provided with an opening registering with a portionof the length of the guide channel, two bending'jaws supported on the base and one slidable in the channel, eachof said jaws having a platform, the upper face of which is flush'with the top of said cover plate and from the opposite ends of which platforms the bending jaws project upwardly and toward one another to permit the slide valve to rest upon said platforms and the flush upper surface of said cover plate, a positioning abutment carried by the cover plate to insure accurat positioning of the slide valve between said jaws, a lever for imparting relative movement to the jaws to bend the tongues of the slide valve to engage with and clamp the flange of a tube associated with said valve. and a stop for limiting the movement of the jaws toward one another to insure uniformity in such bending operations and to preclude crushing of the tube.
